SEALING-DISK FOR BOTTLE-STOPPERS.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JOHN NEUMANN, a citizen of the United States, residing at 1412 Kesner Bldg, Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sealing-Disks for Bottle-Stoppers, of which the following is a specification.

My invention relates to improvements in sealing disks for bottle stoppers, the mode of manufacture of said disks and the improvement in the art of sealing bottles by the aid of said disks.

In the specific embodiment of my improvement herein shown and described, the interior of the flanged fastener cap instead of containing a thin disk of cork as usually employed is provided with a compressible disk of paper formed of two flat circular side portions separated by ,an interposed central circular corrugated is connected at the outer margins of its corrugations to the inner surfaces of the side portions, the whole being dipped and imthen allowed to cool to form a waxen coating upon the outer surfaces and around the edges of the disk.

In manufacturing my improved sealing disks, I prefer to cut the disks to the desired circular form in suitable dies, then dip them in melted wax and finally allow them to cool after which they are ready for use and are fitted in place in the flanged fastener caps.

The cork filling employed in the ordinary stopper is relied 'upon to seal the mouth of the bottle when it is compressed upon the same, with m improved paper disk, the same sealing e ect is secured and at the same time a more perfect, eflicient and complete sealing is obtained around the. edges of the disk by the forcing out of the wax through the compression of the disk which fills all the small interstices between the disk edges and the surface of the. bottle neck.

The objects of my invention are to produce an exceedingly cheap, efiicient and perfect sealing disk forflanged fastener caps for bottles or the like, to so construct these disks that they are quickly and cheaply manufactured, and to so arrange the said disks in the fastener caps that a perfect sealing effect is produced when the caps are forced into place on the mouths of bottles.-

portion which regnated in melted and liquidv wax and posed of Patented J un e 19, 1917. v

The above and other objects I accomplish scription and as particularly pointed out in as hereinafter set forth in the following dethe appended claims reference being had to the accompanying drawings in which an embodnnent of my invention is shown.

In the drawings:

F gure 1', represents a topplan view. of my mproved sealing disk.

Fig. 2, is a central section through the disk on line 22 .Fig. l.

Fig. 3, is a fragmentary view of-the neck of a bottle partially in section with a fastener cap and sealing disk in position thereon. F1g. 4, 1s a fragmentary top plan of a sheet of material from which the disks are cut.

in Fig. 4. In referring to the embodiment of my invention shown in the accompanying draw- Fig. 5, is an edge view of the sheetsho wn ings in detail, like numerals designate corresponding parts.

My improved sealing disk is formedfrom afairly thick compressible composite sheet of suitable material such sheet of suitable material such as corrugated paper impreg;

.nated in and coated with wax.

In the specific embodiment shown in the accompanying drawings, the disk is comtwo companion side portions or sections, 1, which are-flat and circular in form and are in parallel separated arrange-. ment and an interposed corrugated portion 2, arranged between the side portions and connected at its marginal bends to the inner surfaces of the side-portions,

The disk is dipped in a melted and liquid I wax such as heated bees wax after it is cut or the-sheet of material may if in certain circumstances be dipped before the disksare cut therefrom.

After coating the disks are allowed to cool, forming a thin coating 3 of wax on the extension side surfaces of the disk and also at'least partially providing a filling 4 of wax around the circular marginal edge thereof.

My improved disk is inserted in a flanged cap 5, fitting .the same snugly as shown in Fig. 3, and the cap is forced upon the top mouth of a bottle 6 with its depending flange 7 bent inwardly over and locked around \the bead 8 of the bottle neck in the usual manner.

In securing the fastener cap upon the bot tle, the disk is compressed between the top edge of the bottle mouth and the cap, forcing the wax out from between the side portions of the disk and filling all the minute interstices between the circular edge of the disk and the interior of the bottle neck thereby producin a perfect and complete seal which is bot air and liquid tight.

My inap'rovement is especially adapted for bottling beer and other liquids.

When employed in bottles that are heated for sterilization purposes, such as beer botties, the wax in the disk is partially melted by the heat and runs sulficientl to fill in and render the seal more perfect if that were possible.

While I have described and illustrated a preferred form of construction for carrying my invention into efi'ect, the same is capable of a wide ran e of variation, alteration, modification an change without departing from the spirit of my invention, I therefore do not wish to be limited to the above 7 construction but desire to avail myself of all messes within the same by involving the doctrine of equivalents.

What I claim as my invention and desire to secure b Letters Patent is 1. A sea for bottle stoppers comprising a compressible disk having peripheral recesses, and a viscous sealing substance filling said recesses.

2. A sealing disk for bottle stoppers comprising upper and lower cover members, a compressi e corrugated element between said members formin peripheral recesses in the disk, and a wax ike filling in said recesses.

3. A sealing disk for bottle stoppers comprising upper and lower cover members, a compressible mutilated said members forming peripheral recesses in the disk, and a waxlike filling in said recesses.

4. A compressible sealing disk of a plurality of separated paper portions, a bent paper portion connectin said separated gorktions, and a waxlike e ge filling for said 111' testimony whereof I afiix my signature.

JOHN NEUMANN.
